ROBERT F. CAMPBELL, OF BROOKLYN, NEW YORK.

PENDANT FO'R WATCHCASES.

Application filed July 13, 1923. Serial No. 651,213.

T 0 all whom it may concern Be it known that I, ROBERT F. CAMPBELL, a citizen of the United States, and residing at Brooklyn, in the county of Kings, and State of New York, have invented certain new and useful Improvements in Pendants for VVatchcases, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to pendants for watch cases or the frames in which the movements are mounted and particularly to the structure of such pendants and the method of attaching the same to the Watch case and the formation of the watch stem aperture in said pendant and case; and the object of the invention is to provide a pendant of the class specified which is of simple construction and which may be readily mounted in connection with a watch case and secured thereto to produce a strong and durable pendant as well as to reinforcing that portion of the case through which the stem of the watch passes; a further object being to provide a construction of the class and for the purpose specified which is adapted for use principally in comparatively thin watch cases and in which the case is usually weakened in the formation of the aperture therein, through which the stem passes.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, andin which Fig. 1 is a side view of a watch case showing my improved pendant mounted in connection therewith.

Fig. 2 is a diagrammatic view showing a part of a watch case and the pendant spaced apart and illustrating the first step in attaching the pendant to the case.

Fig. 3 is a view similar to Fig. 2 but showing the pendant mounted on the case.

Fig. 4 is a section on the line 44 of Fig. 3 showing the formationof' the stem aperture in the case.

Fig.5 is a section on the line 5-5 of Fig. 4; and,

Fig. 6 is a bottom plan view of the pendant on an enlarged scale.

In Fig. 1 of the drawing T have shown at 10 a watch case of predetermined construction, for illustrating one use of my invention and this case is provided at the periphery thereof with an annular projecting body 11 which is of less dimensions than the transverse dimensions of the case as a whole, as clearly shown in Fig. 4 of the drawing, and at 12 I have shown my improved pendant. In Fig. 1, I have shown at 13 a stem passed through the pendant and watch case but the movement of the watch is omitted.

The pendant 12 comprises a body portion 14 having a downwardly directed oblong and flared extension 15, the lower face of which is preferably curved as shown at 16 to correspond with the curvature of the projecting portion 11 of the casing 10. The pendant 12 is provided centrally thereof with a vertical bore 17, enlarged at its upper end as shown at 18, and the enlargement of the bore extends into a sleeve portion 19 at the top of the pendant and the lower face 16 of the pendant is provided at the opposite sides of the bore 17 and in linetherewith with two downwardly projecting members 20 forming a U-shaped or yoke-shaped projection, and the outer faces of the members 20 are preferably rounded as shown at 21 in Fig. 6 of the drawing.

The projections 20 on the pendant may be formed in many ways; for example, a projecting stud may be formed on the pendant as a whole and this stud milled out to form the separate members 20, or the pendant may have a projecting tubular stud or sleeve which will be milled to form the separate members 20 or the entire pendant may be molded or cast into the form shown and with the bores 17 and 18 therein, or these bores may be drilled after the body of the pendant as a whole has been formed.

In mounting the pendant 12 upon a watch case, after said pendant has been formed in the manner above described, the same is placed on a predetermined point of the case with the members 20' spanning the projecting portion 11 of the case as clearly shown in Fig. 4 of the drawing, and the pendant is secured to the case by soldering, brazing or any other desired manner, but preferably by soldering the curved face 16 of the pendant to the periphery of the projection 11 to attach the pendant to the case as shown in Fig. 3 of the drawing. Assuming that the bores 17 and 18 have been formed in the pendant the next step in building the pendant construction of the case will be to insert a drill of the size of the bore 17 into aperture.

said bore and drill a hole 22 in the casing 10 and through the projection 11 thereof as clearly shown in Figs. 4: and 5 of the drawing. The pendant and case are now in condition to receive the usual watch stem, and it will be noted that that portion of the case 10 or the projection 11 thereof in which the aperture 22 is formed will be reinforced by the members 20 of the pendant which are located at the opposite sides of the projection 11 of the case 10 where the aperture 22 is located.

My improved construction, as will be apparent, materially simplified the mounting of a pendant in connection with a watch case as well as to provide a strong and durable construction and particularly with reference to the reinforcement of the case where the pendant is mounted in connection therewith, and while I have shown a specific form of case as well asa specific form of pendant, it will be understood that I am not necessarily limited in this respect, and various changes in and modifications of the construction herein shown and described may be made within the scope of the appended claims without departing from the spirit of my invention or sacrificing its advantages. -Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A pendant for watch cases of the class described comprising a. pendant body provided with a U-shaped projection adapted to span and reinforce a predetermined portion of a watch case when the pendant is mounted in connection therewith.
